Servus to the scooter community! I have a small problem and maybe you could help me there…?! I bought last week a Gilera Runner Purejet C36 EZ 2004 first hand and with 3200 km for my son. The short test drive ran normal and yesterday I drove with it for the first time and noticed that after about 1.6 km the scooter has short dropouts, as if something was missing sparks, gasoline, air etc. I turned the scooter off briefly, then restarted again et and he ran the next 500m normal again until he started to jerk again briefly, then turned out/started again and the next 500 meters were normal again… The water temperature indicator does not work at all and now of course in many scooter forums the most different opinions are written by defective injection nozzle or the valve, the electronic throttle valve, spark plugs or also the water temperature sensor, this I would probably also at the I think it might be defective and maybe it would always signal engine cold. Have you ever had such problems with your scooters and how are your experiences. I just changed spark plug for a short time because the seller had given me a new one, changed it briefly and he does the same problem. The scooter, the attachments everything looks absolutely new and according to the previous owner there were never (yes, no is clear) problems. I am very happy about every little hint or a short feedback. Check!?????? Daniel and Ben
